I have noticed my unibody gets considerably hotter with the 9600. The whole left palmrest and speaker grill is warm, almost hot to the touch. I'm worried because I just bought a 22" monitor (not here yet) and I plan on using the 17" in clam shell. I don't want to melt the glossy screen or cook the laptop. How hot is too hot? When should I be worried about damage? Today is a hot day. Its 75 degrees F. outside. I have a second monitor running and a handful of programs, PS, Firefox, Word, Acrobat, Entourage, Itunes.
